Biometric ID is characterized as which of the following?

• A. Inherent to a person
• B. Something a person has
• C. Something the person knows
• D. A password

Answer: (A)

Biometric ID relies on traits that are part of the person themselves—physical or behavioral characteristics such as fingerprints, iris patterns, or voice. These are intrinsic to the individual, not something they carry or recall. That’s why biometric methods are tied to “inherent” identity rather than “something you have” (like a badge) or “something you know” (like a password). In practice, a biometric system measures these traits and compares them to stored templates to verify or identify someone. It’s powerful because it’s difficult to imitate or transfer someone’s inherent traits, but it also requires careful handling of privacy and template security.
